HORSESHOE ATTACHMENT.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed August 26, 1914. Serial No. 858,657.

To all whom it may concern:

Be it known that 1, JAMES A. DAVIS, citizen of the United States, residing at Wash ington, in the District of Columbia, have invented certain new and useful Improvements in Horseshoe Attachments, of which the following is a specification.

My invention relates broadly to new and useful improvements in horse shoes, and has particular reference to the provision of a detachable metallic sole which may be se cured to the shoe in such manner as to prevent the frog of the horses hoof from striking rocks or the like.

The principal object of my invention is to accompany the detachable metallic sole with a number of detachable calks and a novel and simple type of fastening means which will serve to secure and firmly attach the sole to the horses hoof.

In connection with the above stated object, I aim to eliminate from the sole fastening means, all bolts and nuts, employing but two screw rods for securing not only the calks, but for also securing the sole in the proper position against the horse shoe.

A further object is to construct the sole plate in two separately formed sections which are adjustably connected whereby the sole may be applied to shoes of varying sizes.

An object of equal importance with the foregoing is to construct the sole and accompanying parts with such regard to proportion, arrangement, and general design, that they may be cheaply manufactured, will be durable and eflicient in service and may be readily attached to any sizeof horse shoe within a reasonable range.

The above recited and other incidental objects of a similar nature, which will be hereinafter more specifically treated, are accomplished by suchmeans as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims, which are appended hereto and form a part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference characters designate corresponding parts, Figure 1 is a bottom view illustrating the sole plate and the accompanying parts in assembled position on a horses hoof, Fig. 2 is a detail perspective view of the sole plate, calk members, and fastening devices in operative assembled relation to each other before application to the horses hoof, Fig. 3 is a side elevation of the horses hoof showing the invention applied thereto, Fig. 4 is a detail rear elevation partly in section of the device removed from the horses hoof. The section shown in this figure is taken on the line H of Fig. 1, Fig. 5 is a section on the line 55 of Fig. 1, Fig. 6 is a detail perspective view of one of the heel calks and the fastening means employed in holding the call: in the proper position, and Fig. 7 is a detail fragmentary perspective view of a modified form of sole plate.

As best shown in Fig. 2 of the acco1npanying drawings, the body portion of the device is formed in the nature of a sole plate which is comprised of two separate sections 10 and 11. The section 10 is preferably formed from two separate metal plates, one of which, indicated individually by the numeral 12, is substantially semi-circular in outline and the other of which, designated by the numeral 13, is substantially rectangular, being provided, however, with curved end edges. The straight edge portion of the member 12 overlaps and bears against the upper face of the forward edge portion of the member 13, being held in the proper position thereon by means of rivets or similar fastening devices, indicated at 14:. lVhile the section 10 of the sole plate is preferably formed from two separate metal plates, it may, of course, be formed as an integral unit in the manner shown best in Fig. 7. Upon reference to this figure, it will be seen that the modified form of the member 10 is formed from a single metallic plate which is bent along a transverse line so as to dispose its rear portion 15 in a plane which is below and parallel to the plane of its forward portion 16.

The section 11 of the sole plate is formed from a single sheet of metal which is folded on a transverse medial line so that the member 11, when completed, includes upper and lower body plates 17 and 18. I he central portion of the sheet of metal from which the member 11 is formed is shaped over a former to produce box shaped brackets or housings 19 and 20, which are separated by a slot 21, as shown in Figs. 1 and 2. The purpose of this slot is to permit access to the heel calk screw rod as will be hereinafter more fully explained. The member 11 is cut away between the members 19 and;

, explained.

In connecting the sections 10 and 11, the forward edge of the memberv 11 is placed upon the upper face of the plate 13and is engaged against the rear edge of the member 12. The, screw bolt, indicated at 23, is then passed through the members 11 and 13. A pair of apertures 24 is preferably provided for the member 11 so thatthe sections may be adjusted to accommodate the sole to horse shoes of different sizes.

I The forward edge portion of the plate 12 is cut away along a chordal line 25 so that the transversely extending toe calk 26 may be flatly engaged against the edge of the member 12. Formed integrally with the toe calk 26 and extending rearwardly from the upper edge thereof is a shoulder plate 27 which is substantially U-shaped and is held in position against the upper face of the member 12 by means of screw bolts 28, as bestshown in Fig. 2. It should be noted that the lower face of the member 27 lies in the same plane as the upper edge 29 of the toe calk. Thus, the edge 30 of the member 27 constitutesa substantially semi-circular shoulder which is adapted to engageagainst the inner edge of the horse shoe, as will be hereinafter explained. I I

7 It is to be noted. that a substantially T- shaped slot or opening is formed in the approximate center of the member 12. a The head portion of this opening, designated by the numeral 31, extends transversely of the plate and the stem portion 32 of the slot extends longitudinally with respect to the plate. The arms of the U-shaped member 27 are arranged so that their inner edges aline vertically with the edges of the portion 32 of the slot.

As a means for detachably securing the forward terminal of the sole plate in position against the horse shoe, I employ a'yoke member 33 which is substantially U-shaped and is adapted to pass transversely across the toe of the horses hoof, as best shown in Fig. 3. The terminals of theyoke 33 are bentat right angles so aswto lie in a hori zontal plane, as indicated at 34. These portions 34, which will be hereinafter referred to as the arms of the yoke, extend diagonally toward the center of the shoe, as shown in Fig. 1, and are connected by an integral transversely disposed bar 35. This bar 35 bears against the lower face of the member 12, as shown in Figs. 3 and 5particularly. Formed integrallywith the bar 35 and at the approximate center thereof, is an upstanding lug 36 which is provided with a threaded bore adapted to receive a screw rod 37. The lug 36 serves not only to receive the screw rod 37 by means of which the yoke is drawn into clamping engagement with the horses hoof, but also serves as a guide'member for the yoke. In this connection, it is to be noted that the lug is in width equal to the width of the stem portion 32 of the T-shaped slot, so that when the lug is moved longitudinally through the slot, its side faces will engage against the edges ofthe slot and cause the yoke to extend, at all times, at right angles to the longitudinalaxis of the sole plate. The screw rod 37 is rounded at its forward terminal and seats in a socket 38 formed in the inner edge of the member 30 at the approximate center thereof. The head 39 of the screw rod is provided with a number of radial bores 40 in which may be inserted a nail, screw driver, or any other similar element for rotating the screw rod. 7 It will be observed, particularly upon reference to Fig.

1, that when the screw rod 37 is threaded through the lug 36, the yoke 33 will be drawn toward the sole plate and engaged with the horses hoof. At the same time the threading of the screw rod through the lug, will cause the spacing of the lug from the member 27 and as a result, the shoulder 30 of this member will engage firmly against the inner edge of the horse shoe.

The rear portion of the sole plate is held in the proper relation to the horseshoe by a pair of laterally extensible clamping plates 41 and 42 which are formed at the terminals of and integrally with a pair of internally threaded sleeve members 43and-44-. These members 43 and 44 are slidably received within the members 19 and 20 and are, there fore, made substantially rectangular in H cross-section, so that they will be held. against rotation within these brackets or housings 19 and 20. A screw rod, indicated at 45, is provided with a square centrally disposed portion 46 which is located in the slot 21 when the terminals of the member 45 are threaded into the members 43 and 44. will, of course, be obvious that the terminal portions of the screw rod 45 are oppositely.

threaded, that is, one is provided with'a left hand thread while the other is provided with a right hand thread, so that the rotation of the member 45 in one direction will cause the clamping plates 41 and 42 to move outward while the rotation of themember '45 in the other direction will cause the plates openings 49 which receivethe spindles 47. The calks 4-8 are, or course, of such size that the distance from the openings 49 to the edges of the calks is less than the distance from the spindles to the upper edges of the members l1 and 42. By thus proportioning the heel calks, the upper portion of each of the members 41 and 42 is exposed for engagement with the inner edges of the horse shoe at the heel portions thereof. 1t is now to be noted that the screw rod 45 may be readily manipulated to extend the members 41 and 42 so that their upper edge portions will clamp firmly against the heel portions of the shoe, thus holding the sole plate against movementrelative thereto. It is also to be noted that the heel calks are held against rotation on the spindles by the engagement of one of their edges with the lower face of the horse shoe. The necessity of providing the V-shaped notches 21 and in the rear edge of the member 11 will now become apparent for it will be seen that these notches are necessary to accommodate the plates 41 and a2 and the calks 48.

Before concluding the description of my device, I desire to direct particular attention to the fact that the employment of nuts in the fastening means ofthe sole plate is eliminated, the entire device being securely held in position on the horse shoe by means of but two screw rods. I have found in eX- periments conducted with other shoes both of my own invention and those at present on the market, that a sole plate which is held in position by nuts almost invariably falls off the horses hoof after being in use only a few hours. The extreme jars and vibration to which the nuts are subjected when the sole plates are attached to heavy draft animals is such as to cause within a short time, the loosening of the nuts and their almost immediate loss. I also desire to direct particular attention to the fact that the heel calks 48 may be turned upon the spindles so as to present at different times, each one of the corners to the road bed. Thus, the heel calks may be used for a relatively long time before it is necessary to substitute new ones or to sharpen the old ones.

Having thus described the invention, what is claimed as new is 1. The combination with a horseshoe, of a device of the character described including a sole plate, a longitudinally adjustable clamping yoke carried by the sole plate, and a pair of laterally extensible clamping plates carried by the sole plate and engageable against the heel portion of the horseshoe for holding the sole plate in position thereon.
